Commercial Waterproofing Contractors — Lee County, FL

Serving Fort Myers, Cape Coral, Bonita Springs, Estero, Lehigh Acres & surrounding areas

Commercial waterproofing is a specialty trade — and most roofing contractors cannot do it. Applying a roof membrane is not the same as waterproofing a below-grade foundation wall, a plaza deck with living load above, a parking garage structure, or a balcony slab. These applications require different products, different installation methods, and manufacturer certifications that most contractors don't hold.

Ocean Group Construction holds active certifications from Sika, Tremco, and Soprema — three of the major manufacturers of commercial waterproofing systems. These certifications are not easy to obtain: they require documented training, inspected installations, and ongoing compliance. They also mean that the waterproofing system we apply carries a real manufacturer warranty, not just a contractor's assurance.

Waterproofing Applications We Serve in Lee County

Below-Grade Waterproofing

Foundation walls, elevator pits, mechanical rooms, and subsurface structures in Lee County's commercial buildings require positive-side or blind-side waterproofing depending on access and construction sequence. Sika and Tremco manufacture the systems we specify for below-grade applications — crystalline, sheet-applied, and fluid-applied membranes matched to substrate conditions and hydrostatic pressure loads.

Plaza Deck Waterproofing

Plaza decks — elevated concrete slabs with pavers, planters, or landscaping above, and occupied space below — are among the most demanding waterproofing applications in commercial construction. Failure means water infiltration into retail, parking, or occupied office space below. We specify and install hot-applied rubberized asphalt, cold-fluid-applied membranes, and traffic-bearing deck coatings appropriate to the loading and use above.

Parking Garage Waterproofing and Traffic Coatings

Lee County's commercial growth has produced a large inventory of parking structures, particularly in Fort Myers's downtown core and Cape Coral's expanding commercial districts. Parking decks take continuous vehicular traffic, UV exposure, and standing water — a combination that degrades unprotected concrete quickly. We install Sika, Tremco, and Soprema traffic-bearing deck coatings and waterproofing membranes for both new construction and restoration.

Balcony and Terrace Waterproofing

Balcony failures in Southwest Florida condominiums and hotels are a significant source of claims and litigation. Podium slabs, balcony decks, and terrace surfaces require waterproofing systems that handle foot traffic, UV exposure, and Florida's thermal cycling. We have specific experience with high-rise and mid-rise balcony restoration in coastal Lee County environments, including Sanibel and Fort Myers Beach where salt-air accelerates coating degradation.

Pool Deck and Mechanical Room Waterproofing

Pool surrounds, equipment rooms, and mechanical spaces require waterproofing products rated for continuous moisture exposure and chemical contact. We specify appropriate systems for each substrate and exposure condition.

Why Manufacturer Certification Matters for Waterproofing

In commercial roofing, the certification question is straightforward: is the contractor certified by the manufacturer whose product they're installing? In waterproofing, this question is even more critical — because waterproofing failures are often hidden for months or years before they manifest as visible damage, and remediation of a failed waterproofing system in an occupied building is extraordinarily expensive.

A Sika, Tremco, or Soprema certification means:

• The applicator has been trained on the specific system and installation method
• The installation is eligible for manufacturer warranty coverage
• The manufacturer can inspect and validate the application on request
• If a product defect causes failure, the manufacturer stands behind the remediation cost

Working with an uncertified contractor on a waterproofing project means you carry 100% of the remediation risk — and in commercial waterproofing, that risk is measured in hundreds of thousands of dollars, not tens of thousands.

What Causes Waterproofing Failures in Lee County Buildings

After years of inspecting and remediating waterproofing failures in Southwest Florida, the causes we see most frequently:

• Wrong product for the application — Using a coating designed for roofing on a below-grade application, or specifying an interior product on an exterior exposure. Products are engineered for specific conditions; substituting them creates liability.
• Inadequate surface preparation — Concrete must be properly profiled and primed before any waterproofing membrane adheres. Skipping or rushing prep work is the most common cause of early delamination.
• Insufficient mil thickness — Fluid-applied membranes must be applied to the manufacturer's specified dry film thickness. Underapplication looks the same as correct application until it fails under hydrostatic pressure.
• Flashing and termination failures — The membrane is only as good as its terminations. Improperly detailed edges, penetrations, and transitions are where most waterproofing failures initiate.
• Deferred maintenance — Surface sealers and traffic coatings on parking decks need periodic reapplication. Waiting until visible concrete deterioration appears means the structural remediation cost has already multiplied.

Request a Waterproofing Assessment

If you have a building in Lee County with active water infiltration, a scheduled maintenance inspection, or a new construction project requiring waterproofing scope, contact us for an assessment. We'll evaluate the application, recommend the appropriate system and manufacturer, and provide a written proposal with product specifications and warranty terms.
